Description

휴대폰 배터리 팩( Battery pack for portable phones )Battery pack for portable phones

본 고안은 휴대폰 배터리 팩에 관한 것이며, 보다 상세히는 내부에 자체 충전 기능이 구비된 휴대폰 배터리 팩에 관한 것이다.The present invention relates to a mobile phone battery pack, and more particularly to a mobile phone battery pack having a self-charging function therein.

일반적으로 휴대폰 배터리 팩은 휴대폰용 전원으로 사용되는 배터리(예컨대, 리튬 이온 배터리)를 내장하는 전원 장치로서 휴대폰 본체에 체결된다.In general, a mobile phone battery pack is fastened to a mobile phone main body as a power supply that contains a battery (eg, a lithium ion battery) used as a power source for a mobile phone.

특히, 상기 배터리는 그 사용 시간이 한정되어 있으므로 데스크 충전기와 이동 충전기 등을 사용하여 수시로 충전할 수 있도록 되어 있다.In particular, since the use time of the battery is limited, the battery can be charged at any time using a desk charger, a mobile charger, or the like.

즉, 종래에는 상기 휴대폰 배터리 팩을 데스크 충전기와 이동 충전기 등의 데스크 홀더에 연결하거나 상기 휴대폰 배터리 팩이 체결된 휴대폰 자체를 데스크 홀더에 연결하여 상기 배터리를 급속 충전하도록 되어 있다.That is, conventionally, the mobile phone battery pack is connected to a desk holder such as a desk charger and a mobile charger, or the mobile phone itself to which the mobile phone battery pack is fastened is connected to the desk holder to rapidly charge the battery.

그러나, 상기와 같이 데스크 충전기와 이동 충전기 등을 사용하여 배터리를 충전하게 되면 데스크 홀더에 배터리 팩이 연결되었는지 또는 배터리 팩이 체결된 휴대폰 자체가 연결되었는지를 감지하기 위한 기능과 데스크 홀더에 연결되는 배터리 팩이나 휴대폰의 사이즈를 검출하기 위한 기능, 배터리 팩이나 휴대폰이 상기 데스크 홀더에 정상적으로 접촉되었는가를 확인하기 위한 기능 등과 같은 다수의 부가적인 기능이 필요하게 되므로 충전 회로가 복잡해지는 문제점이 있다.However, when the battery is charged using the desk charger and the mobile charger as described above, the battery connected to the desk holder and the function for detecting whether the battery pack is connected to the desk holder or the mobile phone to which the battery pack is connected is connected. Since a number of additional functions such as a function for detecting the size of the pack or the mobile phone and a function for checking whether the battery pack or the mobile phone is normally in contact with the desk holder are required, the charging circuit is complicated.

또한, 여행 중 또는 출장 중인 휴대폰 사용자는 상기와 같은 데스크 충전기와 이동 충전기 등을 가지고 다녀야 하는 불편함이 있다.In addition, the user of the mobile phone while traveling or traveling is inconvenient to carry a desk charger and a mobile charger as described above.

따라서, 본 고안은 상술한 종래의 문제점을 극복하기 위한 것으로서, 본 고안의 목적은 내부에 자체 충전 기능이 구비된 휴대폰 배터리 팩을 제공하는데 있다.Accordingly, an object of the present invention is to provide a mobile phone battery pack having a self charging function therein.

LED부(50)는 케이스(10)의 뒷면 소정 부위에 장착되며 상기 충전 회로(40)의 출력 상태와 배터리(30)의 충전 상태의 이상 여부를 표시한다.The LED unit 50 is mounted on a predetermined portion of the rear side of the case 10 and displays whether the output state of the charging circuit 40 and the charging state of the battery 30 are abnormal.

상기 LED부(50)는 배터리(30)의 충전이 완료되거나 보상 충전 또는 예비 충전 중일 때, 과전류 및 과전압이 상기 충전 회로(40)와 배터리(30)로 인가될 때, 배터리(30)의 내부 온도가 허용 온도 범위를 초과하여 대기 중일 때 그 이상 여부를 표시한다.The LED unit 50 is inside of the battery 30 when overcurrent and overvoltage are applied to the charging circuit 40 and the battery 30 when the charging of the battery 30 is completed or during compensatory charging or precharging. Indicates if the temperature is above the allowable temperature range and is in the air.

접촉 단자(60)는 케이스(10)가 휴대폰과 접촉하는 면쪽에 장착되며 사용자가 본 고안에 따른 배터리 팩을 휴대폰에 체결하면 배터리(30)의 충전 전원이 휴대폰에 공급되도록 한다.The contact terminal 60 is mounted on the side where the case 10 contacts the mobile phone and when the user fastens the battery pack according to the present invention to the mobile phone, the charging power of the battery 30 is supplied to the mobile phone.

상기와 같은 구성에 의해서 본 고안에 따른 휴대폰 배터리 팩은 다음과 같이 작동한다.By the above configuration, the mobile phone battery pack according to the present invention operates as follows.

휴대폰 사용자가 케이스(10)의 홈 안에 부착되어 있는 플러그(20)를 90。로 펼친 후 가정용 전원 콘센트에 꽂으면 200V 가정용 전원이 상기 플러그(20)를 경유하여 상기 충전 회로(40)로 인가된다.When the mobile phone user unfolds the plug 20 attached to the groove of the case 10 to 90 ° and plugs it into a household power outlet, 200V household power is applied to the charging circuit 40 via the plug 20. .

따라서, 상기 충전 회로(40)는 상기 200V 가정용 전원을 휴대폰 전원으로 사용할 수 있는 충전 전원으로 변환하여 배터리(30)를 충전시킨다.Thus, the charging circuit 40 converts the 200V home power into charging power that can be used as a mobile phone power to charge the battery 30.

또한, 상기 충전 회로(40)에 의해 배터리(30)가 완전히 충전되거나 충전되는 도중에 상기 LED부(50)는 상기 충전 회로(40)의 출력 상태와 배터리(30)의 충전 상태를 감지하여 그 이상 여부를 표시한다.In addition, the LED unit 50 detects the output state of the charging circuit 40 and the charging state of the battery 30 while the battery 30 is fully charged or charged by the charging circuit 40. Indicate whether or not.

상기 충전 회로(40)에 의해 배터리(30)가 완전히 충전된 후 사용자가 본 고안에 따른 배터리 팩을 휴대폰에 체결하면 이때부터 상기 접촉 단자(60)를 통해 배터리(30)의 충전 전원이 휴대폰으로 공급된다.After the battery 30 is fully charged by the charging circuit 40, when the user fastens the battery pack according to the present invention to the mobile phone, the charging power of the battery 30 is transferred to the mobile phone through the contact terminal 60. Supplied.

본 고안에 따른 휴대폰 배터리 팩은 휴대폰에 체결한 상태에서도 상기 플러그(20)를 가정용 전원 콘센트에 꽂아 사용할 수 있다.The mobile phone battery pack according to the present invention can be used by plugging the plug 20 into a home power outlet even when it is fastened to a mobile phone.

한편, 도 3을 참조하면 상기 케이스(10)에 내장되는 충전 회로(40)는 다음과 같이 작동하여 배터리(30)에 충전 전원을 공급한다.Meanwhile, referring to FIG. 3, the charging circuit 40 embedded in the case 10 operates as follows to supply charging power to the battery 30.

상기 플러그(20)를 통해 상기 충전 회로(40)로 인가되는 200V 가정용 전원은 제1 필터 회로(42)와 제1 정류 회로(43)에 의해 필터링되고 정류되어 안정화 된 후, 절연 변압기(45)에 의해 휴대폰 전원으로 사용할 수 있는 소정의 충전 전원으로 변환된다.After the 200V household power applied to the charging circuit 40 through the plug 20 is filtered, rectified and stabilized by the first filter circuit 42 and the first rectifier circuit 43, the isolation transformer 45 is applied. Is converted into a predetermined charging power source that can be used as a mobile phone power supply.

이때, 과전압 보호 회로(41)와 과전류 보호 회로(44)에 의해 상기 절연 변압기(45)로 인가되는 가정용 전원에 포함된 과전류 또는 과전압 성분이 감지되면 상기 LED부(50)가 작동하여 그 이상 여부를 표시한다.At this time, if an overcurrent or overvoltage component included in the home power applied to the isolation transformer 45 is detected by the overvoltage protection circuit 41 and the overcurrent protection circuit 44, the LED unit 50 operates and is no longer there. Is displayed.

또한, 상기 절연 변압기(45)로부터 출력되는 소정의 충전 전원은 제2 정류 회로(46)와 제2 필터 회로(47)에 의해 최종적으로 안정화 된 후, 상기 배터리(30)로 공급된다.In addition, the predetermined charging power output from the isolation transformer 45 is finally stabilized by the second rectifying circuit 46 and the second filter circuit 47 and then supplied to the battery 30.

이때도 역시, 충전 전류 감시 회로(48)에 의해 상기 배터리(30)로 인가되는 전원에 포함된 이상 전류가 감지되면 상기 LED부(50)가 작동하여 그 이상 여부를 표시한다.In this case, too, when the abnormal current included in the power applied to the battery 30 is sensed by the charging current monitoring circuit 48, the LED unit 50 operates to indicate whether there is an abnormality.

상술한 바와 같이 본 고안에 따른 휴대폰 배터리 팩은 플러그를 가정용 전원 콘센트에 직접 꽂고 케이스에 내장된 충전 회로에 의해 배터리를 충전하도록 되어 있기 때문에, 종래의 데스크 충전기와 이동 충전기 등을 사용하지 않고서 간편하게 배터리를 충전할 수 있으며 충전 회로 역시 종래에 비해 더욱더 간소화할 수 있는 효과가 있다.As described above, the mobile phone battery pack according to the present invention is designed to directly plug a plug into a home power outlet and to charge the battery by a charging circuit built into the case. It can be charged and the charging circuit also has an effect that can be further simplified compared to the conventional.

이상에서 설명한 것은 본 고안에 따른 휴대폰 배터리 팩을 실시하기 위한 하나의 실시예에 불과한 것으로서, 본 고안은 상기한 실시예에 한정되지 않고, 이하의 실용신안등록청구의 범위에서 청구하는 본 고안의 요지를 벗어남이 없이 당해 고안이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경 실시가 가능할 것이다.What has been described above is only one embodiment for implementing a mobile phone battery pack according to the present invention, the present invention is not limited to the above embodiment, the subject matter of the present invention claimed in the following utility model registration claims Any person having ordinary knowledge in the field to which the present invention pertains may make various changes without departing from the scope of the present invention.
